The Japanesse did also built a few dedicated Kamikaze planes. I have shots of one in a book called
Pacific War Eagles In Color or something like that. They were ugly A/C, totally purpose built.
The landing gear had no struts and either fell of on take off or were jettisoned.
They were unpainted, except for the meatball, and they were of such a low grade metal, they arrived at the airfield with rust on them.
Also they had no canopy, just a windscreen.
These were built because they were much cheaper than their front line stuff, and could be built by very unskilled laborers.
